SPECIFICATION forming part of Letters Patent No. 262,819, dated August15, 1882.

Application filed February 2, 1882. (N0 model.)

To all whom it may conctrn Beit known that I, TRUMAN O. NARAMORE, a

citizen of the United States of America, residing at NVilliston, in thecounty of Ohittenden and State of Vermont, have invented certain new anduseful Improvements in Railroad Tie and ItailElevators; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilledin the art to which itappertains to make and use the same, reference being hadto theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

My invention relates to improvements in devices for raising heavyweights, and is especially adapted to the raising of railroad ties andrails.

It consists in so arrangingand combining the mechanism employed thatwhile it possesses the essential characteristics of simplicity,cheapness, and durabilityin its construction, its application of poweris most economical and effective.

It consists of a metallic frame so designed as to sustain one or moregear-wheels, with their respective drums, operated by a lever-socketpinion, having an independent attachment to the upper extremity of theframe, so that the power can be conveniently applied on either side ofthe frame at the fulcrum on the ends of the fulcrum supports or braces.One or more spring dogs or pawls serve to take the strain of the liftand prevent reverse motion while resetting the socket-pinion. The weightis thus always on the upper or dog shaft, which is located directly overthe center of the frame and on aline perpendicular to that portion ofthe lifting-chain to which the weight is attached by means of agrappling-iron of novel con struction.

I attain these objects by the mechanism illustrated in the accompanyingdrawings, in which Figure 1 is a perspective of my invention. Fig. 2 isa side elevation of the same. Figs. 3 and 4 are side elevations of thegrappling-irons.

Similar letters refer to similar parts throughout the several views.

A is a metallic frame, the two sides of which I prefer to maketriangular in form, connected together at each angle, and designed to besustained by the stanchions B B, which are suitably braced, and to theupper extremities of which they are attached. Through the angle, at theapex, passes a bolt, a, which forms the shaft of the spring dog or pawl12 and sustains the fulcrum-braces c 0. Through one of the angles, atthe base, passes the shaft 01 of the gear-wheel O and drum D, which iscast solid to one or both sides of the gear-wheel O.

c c are slotted supports on either side of the fulcrum-braces c 0, andwhich are pinioned to the base of the frame A atff.

E is a lever-socket pinion, made of metal, having a socket at one end,into which a lever, F, is fitted. The other extremity is a segment of apinion, having teeth designed to engage with the teeth of the gear-wheelO. The pinion E revolves upon a pin or bolt, which passes through theextremities of the braces c o and the slotted holes of the supports 0 0,and thus forms a fulcrum of the lever F. The projecting ends h h of thepinion E, together with its connection with the supporting-braces c cand e c, serve to retain the pinion rigidly in place while meshing withthe gear-wheel G.

G is a chain which is fastened to the drum, passing over it to the sidetoward the pinion E. It terminates in the grappling-iron H,which iscomposed of the double straps it, the curved arms jj, and the doublesupporting-braces 70. To the upper extremity of the straps'i the chain Gis attached, one end of the double braces being pivoted to the lower endof the straps 5 and the other on each side of the lower part of thearmsj respectively. The upper extremities of the arms j are hingedtogether so as to slide freely between the straps i By this arrangementthe upper portion of the arms j always form a guide to keep their lowerparts or hooks in a reliable position, the weight being wholly sustainedby the double braces k and the hooks, so that whatever may be the sizeof the weight to be elevated it is always readily and firmly grasped bythe grappling-iron H. By working the lever F the gear-wheel O isrevolved, thus winding up the chain G on the drum and raising the Weightto which the grappling-iron H is attached. The strain is always on thedogshaft to directly over the weight, the power being applied at thefulcrum g, the dog-brace thereby sustaining the weight, so that it istransmitted below to a point just as far from the center as is the axleof the gear-wheel C. The dog I) is braced by the fulcrum-brace, whichsustains the lever when the dog is not holding.

By elevating theleverF it is at once thrown out of gear, and the weightis more or less rapidly lowered, according as the socket may be used asa brake. As the connections are all above the wheel 0, it is apparentthat the apparatus can be worked either at the top or sides or whereverit is most convenient; or, if desired, the lever can be reversed andworked upon the other side. By means of a double dog at the top, and byconnecting the lever with double-slotted braces below, the gearwheel canbe turned the other way by raising the lever. In brief, the apparatus issusceptible of being used in every position where a TRUMAN O. NARAMORE.
